一. 拉取Oracle 19c镜像

[root@centos ~]# docker pull registry.cn-hangzhou.aliyuncs.com/zhuyijun/oracle:19c
19c: Pulling from zhuyijun/oracle
bce8f778fef0: Pull complete 
3fc3fd32c0bc: Pull complete 
02948dd6d654: Pull complete 
67f2dfeb2f1b: Pull complete 
2e42d8039fd9: Pull complete 
b94f01bb60c6: Pull complete 
Digest: sha256:3898a9394720f30ce7f0b83ef2d172f4cd11b958282e0505f83cf2b0e5eaf7d4
Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/zhuyijun/oracle:19c
registry.cn-hangzhou.aliyuncs.com/zhuyijun/oracle:19c

二. 查看镜像

[root@centos ~]# docker images
REPOSITORY                                          TAG       IMAGE ID       CREATED         SIZE
registry.cn-hangzhou.aliyuncs.com/zhuyijun/oracle   19c       7b5eb4597688   20 months ago   6.61GB
oracleinanutshell/oracle-xe-11g                     latest    ad13c30ec346   3 years ago     2.13GB

三. 创建Oracle 19c镜像的容器
3.1创建目录

mkdir /opt/oradata
chmod -R 777 /opt/oradata/

3.2 创建实例

docker run -d -it --name oracle19c -p 1521:1521 -p 5500:5500 -v /opt/oradata:/opt/oracle/oradata registry.cn-hangzhou.aliyuncs.com/zhuyijun/oracle:19c

3.3 查看日志

[root@centos ~]# docker logs -f oracle19c

四、 修改密码

# 系统默认的system密码修改成oracle
docker exec oracle19c ./setPassword.sh oracle

setPassword.sh 脚本如下

[root@centos ~]# docker exec -it oracle19c /bin/bash
[oracle@centos ~]$ ls
setPassword.sh
[oracle@centos ~]$ pwd
/home/oracle
[oracle@centos ~]$ cat setPassword.sh 
#!/bin/bash

ORACLE_PWD=$1
ORACLE_SID="`grep $ORACLE_HOME /etc/oratab | cut -d: -f1`"
ORACLE_PDB="`ls -dl $ORACLE_BASE/oradata/$ORACLE_SID/*/ | grep -v pdbseed | awk '{print $9}' | cut -d/ -f6`"
ORAENV_ASK=NO
source oraenv
 
sqlplus / as sysdba << EOF
      ALTER USER SYS IDENTIFIED BY "$ORACLE_PWD";
      ALTER USER SYSTEM IDENTIFIED BY "$ORACLE_PWD";
      ALTER SESSION SET CONTAINER=$ORACLE_PDB;
      ALTER USER PDBADMIN IDENTIFIED BY "$ORACLE_PWD";
      exit;
EOF

五、连接数据库

sqlplus system/oracle@xxx.xxx.xxx.xxx:1521/ORCLCDB

5.1测试方案一：进入容器内部测试

[root@centos ~]# docker exec -it oracle19c /bin/bash
[oracle@centos ~]$ sqlplus system/oracle@localhost:1521/ORCLCDB
 
SQL*Plus: Release 19.0.0.0.0 - Production on Thu Apr 7 01:54:17 2022

5.2测试方案二：用navicat连接测试

[root@centos ~]# docker exec -it oracle19c /bin/bash
[oracle@centos ~]$ cd /opt/oracle/product/19c/dbhome_1/network/admin/
[oracle@centos admin]$ ls
listener.ora  samples  shrept.lst  sqlnet.ora  tnsnames.ora

SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8
SQLNET.ALLOWED_LOGON_VERSION_SERVER=8
[oracle@centos admin]$ exit
exit
[root@centos ~]# docker ps -a
